Good Soldier, here is a salutary lesson. Some years ago I had a wonderful review of my album in a Scottish folk magazine. It was written by a well respected performer known for his quiet style and integrity. (Sadly he is no longer with us). It followed your guidelines and was informative even about things that were not in the sleeve notes. It made him look learned and the album sound well worth anybody's money. So it should as I was sitting next to him while he wrote it. "That's the way to do it".
